Dronee - How to set sony RX0 to get perfect mapping results.

Hi everyone,

I would like to share my experience with Sony RX0 which is a fantastic camera for surveying.

SonyRX0 zero is a small size, a shockproof digital camera with 25 mm wide angle (equivalent to 35mm)

It is only 110 gram with battery. Quality, size, wight make it suitable for surveying applications on drones.

Sony RX0 has a manual mode to set all camera parameters manually to get sharp pictures 

to get sharp quality pictures you should consider to set few parameters correctly:

Shutter speed: to remove blur from photo shutter speed should be set for higher value. 1200–1600 is recommended. Higher the shutter speed reduce image quality.

ISO: lower the ISO higher image quality. ISO between 150–300 is recommended.

Focus: Recommended to set the focus manually on the ground before the flight. Direct camera to an object which is far, and slightly increase the focus, you will see on camera screen that image sharpness changes by changing the value. Set the image sharpness at highest.

White balance: recommended to set to auto.

Comparison with Google Maps

Dronee PLANE fully supports Sony RX0 camera and triggers the camera over onboard wifi.

Cheers,

Tomi

I don't see any reason to geotag photos if you don't have a very precise feedback from camera (<5ms). If you manage to solve this problem I think there will be a lot of clients ready to spend more than 1k USD for the mod but I also realize this is not an easy job, others tried with QX1 and had almost no result. Sensefly is doing this but with much more friendly cameras. RAW is much better than any JPG, tested.

Hi @TomiPiriyev 

I'm trying to trigger the RXO, but have had no such luck. I purchased a Sony multi servo wire from flytron. I've tried every trigger mode available on QGroundControl (GPIO, SeaGull Map2, Generic PWM) using AUX 56. nothing seems to work. Do I need to set the trigger signal frequency to something specific. I also own a Sony a6000 and I haven't been able to trigger it either. I know I'm missing a critical step here, but I can't seem to figure it out. Your support would be greatly appreciate. Look forward to hearing from you soon. 

Kind Regards,

Hi Ryan,

Try trigger a6000 first, it's really easy !

Hi @kiki boy,

I noticed the micro USB only has 3 wires. I just stripped a spare one and it has 5 wires (red, blk, gre, wht, and copper). Curious if you familiar with this 5 pin micro USB and what wires need to be soldered to the servo wire. Hoping to trouble shoot this tonight. If I have to buy the camera trigger micro USB outlined in the docs then I'm probably better off ordering a Seagull Map2 trigger. Look forward to hearing from you sooon.

@kiki boy,

The microUSB wires are as follows... Red (VCC), White (D+), Green (D-), Black (GND). Since this is not a traditional trigger wire as displayed in the pdf, how do you recommend I wire these to a servo wire? Also, do you know if the micro USB in the pdf is a multi port, because Sony has a special 10 pin header.

Yes it's a multiport on pdf !

I made a cable to power on/off and trigger. I use it in RX100, A6000. Watch here : https://www.youtube.com/watch?v=AEqcMNUSbl4

First what you need to know is you have to test it without flight controller.

Do you have a link to your cable ? If it's 5 pin it will not work. Sony triggering will work only on multiport : focus + triggerring need to be shorten with ground and these focus + trigger pad are on multiport not classic 5 pin

The only Multiport USB I have is one that I purchased from flytron, which is not working unfortunately. It has 5v of electricity on AUX5. So I'm not entirely sure why It's not triggering. Based on their wire, do you suggest I cut the Sony multiport wire and solder directly onto the servo wires. If so I would need to know what colour attaches where.

Please send link to this flytron cable

Ok ! Do not need to cut ...

You could try without connecting to pixhawk. With a paperclip, power your camera and connect your paperclip to ground and white servo pin, it should trigger !

Then share your ardupilot parameters

CAM_TRIGG_TYPE:

CAM_SERVO_ON:

CAM_SERVO_OFF:

CAM_RELAY_ON:

CAM_AUTO_ONLY:

RELAY_PIN:

BRD_PWM_COUNT:

Did you power servo wire ? Which model of piwhawk are you using and which firmware ?
